Abstract: A jig is used in place of a master Cathode Ray Tube (“CRT”) for calibrating a Stray Emissions Detection System (“SEDS”). Light Emitting Diodes (“LEDs”) are placed in the neck portion of a CRT, where the electron gun would normally be disposed, to form the test jig. These LEDs are activated during the calibration process to simulate the stray emissions that would be released through defects in a CRT. Because the number, pattern and light output of the LEDs can be controlled, and are not changed by the calibration procedure itself, the jig can be used to more reliably and effectively calibrate the SEDS for CRT manufacture.

Abstract: A system for utilizing solar energy efficiently in air conditioning systems during the heating mode having at the evaporator heat exchange means which extracts the heat from ambient air when the latter is greater than 47.degree. F. and from solar heated fluid when the ambient air is less than 47.degree. F.

Abstract: A metering valve device being particularly adapted for the precision control of metering minute quantities of fluids and the like from a high pressure environment to a low pressure environment, even to a vacuum. The metering valve device having a cylindrical core and an inlet and an outlet. The inlet is connected to a radially disposed duct that extends to and forms an opening on the surface of the core, while the outlet is connected to a V-shaped slot positioned on the surface of the core in space relation to the opening. A sleeve that is slidably mounted on the core has a portion that forms a leakproof chamber between the core and the sleeve at the position of the opening and a seal-tight engagement of the core at the position of the V-shaped slot. Upon sliding the sleeve so as to permit a desired part of the V-shaped slot to be brought within the confines of the chamber, a controlled volume of high pressure fluid may be dispensed through the device.
